ABSTRACT Real-time intrafraction tracking/gating is an integral component of MRI-guided radiotherapy (MRgRT), and may have contributed to the acute toxicity reduction during prostate stereotactic body radiotherapy (SBRT) observed on the MRgRT-arm of the MIRAGE randomized trial (NCT04384770). Herein we characterized intrafraction prostate motion and assessed gating effectiveness. Seventy-nine patients were treated on an MR-LINAC. Real-time cine imaging was acquired at 4Hz in a sagittal plane.
